  1. Why doesn't my 7.3 go like it should!

    99-03 7.3L General Discussion
    I have a 2000 f350 7.3 with a zf6 I have 160/80's, regulated return, 550 hp clutch, custom tuning from gearhead, intake, exhaust, ect. It doesn't go much better than when I just had an out of the box TS chip. It peaks at 29lbs on the stock turbo, and I've used an AE on it and everything checks...
